Technology's opening live broadcast to build rockets

"Xiaoyu has landed on Mars!" Du Xingyu's parents learned the news immediately.

"The landing was successful!" Everyone in Xingyao Company and Chengfeng Space Company was celebrating.

In front of the TV and the Internet, there are also a large number of viewers congratulating and cheering for it.

Two hours later, on Mars, in Chris Plains, everyone decided on the location of the base.

It is a lava plain on the back of a crater. The crater can block the dust storms that often sweep across Mars; the Martian sand and gravel on the surface can be used as building materials. The surrounding view is wide and the terrain is flat, making it a good choice.

"The target camp location is about an hour away from the Yinghuo." Xu Lianqiu looked at the specially made watch and said, "We must return before 6 p.m. Mars time. This is the safest and safest way."

"Let's go!" The Yinghuo Mars spacecraft carried two folding Mars rovers. Everyone sat on the Mars rover, carrying supplies, and followed an electric trolley composed of modular robots behind them, heading to the target location.

While riding in the car, Du Xingyu slightly cut out the footage captured by the camera and posted it to his Douyin "Earth Observation" account.

"Updated again?" Du Xingyu's Douyin fans saw the latest video as soon as they opened the app.

In the picture, Du Xingyu takes mankind’s first footprints on Mars!

"6666!"

"We've officially landed on Mars!"

"(Expression: I admit you are a little bit awesome.)"

“I saw it on Douyin before the news appeared! I’m so excited!”

"Now that we have landed on Mars, we need to find a suitable location to build a Mars base..." Du Xingyu explained in the video.

"Okay, everyone, we have found the location and are ready to go!"

The video was cut off, leaving the audience still wanting more.

"The author is too short!"

"It's only a little bit, I still want to see it!"

" @Maruko-chan, watch the new show - "Surviving Mars"!"

"Isn't this much better than a variety show?"

"Follow it, pay attention!!! Please follow the next episode!"

In just a few hours, Du Xingyu’s Douyin fans increased to more than 5 million! And as his videos enter the hot video list, the rate is still increasing!

On Mars, Du Xingyu led the team to the target location.

Below are broad lava plains covered with a layer of sand and gravel. Farther away is a ring of mountains, which was formed by meteorite impacts in Mars' ancient times.

"Start work!" Du Xingyu gave the order and everyone started working.

They first opened an inflatable radiation-proof tent. Although they had space suits to protect against radiation, they still could not be exposed to the surface environment for a long time, as this would cause damage to their bodies.

Su Peng and others controlled the modular robot and began to lay the foundation for the base. They collected sand and gravel and handed them to the 3D printing robot to lay the foundation.

Xu Lianqiu and Xu Rui went to install portable signal stations for communication and environmental monitoring equipment.

This seemingly peaceful Mars actually hides countless dangers. The weird and changeable natural environment is their biggest enemy!

Modular robots are constantly working, and the foundation of the Mars base is being laid rapidly. The process is similar to that in Du Xingyu's previous video. The printed Martian mud is stacked layer by layer on the ground to form an ant nest-like shell.

When the shell is laid, they will build another wall with dry ice and soil for insulation and radiation protection.

The Mars construction site is in full swing. A few kilometers away from the construction site, Xu Lianqiu and Xu Rui are installing a wind speed alarm. It is driven by a microprocessor and a highly dynamic wind sensor and can monitor the surrounding air flow. and speed.

"Huh?" Xu Lianqiu suddenly sounded suspicious and said, "Xu Rui, do you feel that the wind speed is abnormal?"

"Abnormal?" Xu Rui looked at the instrument and said, "There are some fluctuations, but they should be within the normal range. The alarm also shows normal."

"That's wrong!" Xu Lianqiu frowned slightly and said, "Do you still remember the knowledge we learned in the simulated Mars base? The composition and structure of the Martian atmosphere are different from those of the Earth. We cannot use the standards on the Earth to judge."

She looked at the instrument carefully and said: "The airflow has accelerated, the wind direction has changed... there may be a sudden dust storm!"

Martian dust storms are natural disasters that often occur on Mars, occurring hundreds of times almost every year. At some times, huge Martian dust storms will even last for several years, and dust with a particle size of 10 microns will be blown thousands of meters into the sky, blocking the sky and the sun!

Mars synchronous satellites have been monitoring the meteorological conditions above the landing site, but it is difficult for satellites to predict local sudden changes in advance.

"There was no sign of dust storm before we landed... But you are right, the atmosphere here changes too fast, we should inform the captain and the others in advance." Xu Rui shouted into the communicator, "Captain, this is Xu Rui, We found that the airflow changes nearby increased, which may trigger dust devils!"

"Dust storm?" Du Xingyu was controlling the robot to build a wall at this time. Hearing Xu Rui's words, he looked around.

The surroundings seemed very calm, with only a slight breeze blowing the sand.

"Are you sure?" Du Xingyu asked again.

"Sixty percent possibility." Xu Lianqiu said on the communication channel, "There is too little data and it is difficult to make accurate predictions. I suggest stopping work immediately and preparing to return."

"Okay!" Du Xingyu said directly in the team channel, "All team members, immediately suspend construction and scientific research tasks, gather to call it a day, and prepare to return to the spacecraft!"

Before the base is built, there is no need for them to gamble even if there is only a 10% chance. Anyway, there is plenty of time, but you only live once!

Xu Lianqiu and Xu Rui rode on Mars motorcycles and ran towards Du Xingyu.

On the construction site, everyone began to immediately pack up tools and supplies and put them on a cart composed of modular robots, preparing to return to the spacecraft.

At this time, the wind speed alarm had started to sound, and the wind speed began to surge in a short period of time. There was a whistling wind in the distance, and you could see with the naked eye that on the other side of the lava plain, yellow sand filled the air, like an army of thousands of horses, running towards Du Xingyu and others.

"It's too late to go back!" Xu Lianqiu shouted to Du Xingyu in an anxious tone, "The wind is faster than us. It will take an hour to go back, and we will be overtaken by the dust storm! It's best to hide on the spot!"

Du Xingyu knew that his decision at this time was related to the lives of the team members.

He thought of the content of the training in the simulated Mars base and hurriedly shouted: "Everyone should stop the task immediately, lie down behind the mud wall, and cover themselves with shelter! Remember, never poke your head, protect yourself, and wait for the dust storm past!"

Du Xingyu knew very well that the Chris Plains where they chose to land would not cause a large-scale dust storm due to its geographical environment. This must be a sudden local dust storm.

The atmosphere of Mars is thin, only one percent that of the Earth, and the wind power of local dust storms is limited. It is impossible to blow away the Mars rover and spacecraft like in science fiction movies.

The mud wall built by the modular robot just now is a sloped pile structure, which will block most of the wind and sand.

As long as the appropriate measures are taken, the crisis can be dealt with!

Thanks to Sanyou Sanyang, Xinbenwuya, and Xuan Ruiyuyu for the reward.
